Description

Technical Field

[0001] The invention relates to the technical field of pipeline pre-embedding, and in particular to a grooving method for pre-embedding pipelines of roads and bridges. Background Art

[0002] After the road is paved, it is sometimes necessary to groove the asphalt or cement road surface to discharge water pipes, gas pipes and other pipelines. Therefore, a grooving device is needed. When the grooving device grooves the road surface, a large amount of dust will be generated. The flying dust will pollute the environment around the workplace. The existing grooving device cannot reduce dust, which will affect the health of people after inhalation. Patent documents have been made to improve this.

[0003] For example, Chinese patent CN212128799U discloses a grooving device for pre-buried pipelines of roads and bridges, comprising a base box, the inner cavity of the base box is fixedly connected to a battery, the four corners of the bottom of the base box are fixedly connected to wheels, the left side of the top of the base box is fixedly connected to a water tank, the top of the water tank is connected to a water injection funnel, the bottom of the right side of the water tank is connected to a water pump, the water outlet of the water pump is connected to a water pipe, the right side of the top of the base box is fixedly connected to a vertical plate, and the top of the right side of the vertical plate is fixedly connected to a fixed plate. The utility model has the advantages of being able to reduce dust on the road surface during grooving, which is beneficial to the health of personnel, by providing a base box, wheels, a water tank, a water injection funnel, a water pump, a water pipe, a vertical plate, a fixed plate, an electric telescopic rod, a protective cover, a grooved wheel, a nozzle, a battery, a motor, a movable rod, a slide, a fixed rod, a threaded rod, a slider and a turning handle for coordinated use.

[0004] Although the equipment in the above document reduces dust generated by the equipment during slotting by spraying water mist, its overall functionality is single and also has defects, such as:

[0005] When the equipment is used, it only relies on the slotting wheel to make slots. However, the surface of the slotting wheel is generally attached with raised grinding blocks, so the side wall of the pipe groove will be uneven during the slotting. At the same time, a large number of impurities such as stones will be left inside the pipe groove, and the staff will need to perform secondary processing later, which increases the labor and the process is cumbersome.

[0006] Therefore, a kind of pre-buried grooving equipment for road and bridge pipelines capable of grinding and cleaning the pipe groove is now designed to solve such defects. Summary of the invention

[0007] In view of the deficiencies in the prior art, the present invention provides a grooving method for pre-buried road and bridge pipelines, which solves the problem that the existing grooving equipment has a single function, and the internal unevenness after grooving has many impurities and requires secondary processing, which increases the labor workload.

Beneficial Effects

[0024] The present invention provides a grooving method for pre-embedded pipelines in roads and bridges. Compared with the existing technology, it has the following beneficial effects:

[0025] (1) The grooving method for pre-buried pipelines of roads and bridges is achieved by combining a basic linkage mechanism and a grinding drive mechanism. The two mechanisms can spray water mist to reduce dust during grooving, and can also use a cutting wheel to cut in advance to improve flatness. After grooving a certain distance, the power connection and linkage between the structures can be used to drive the grinding disc and the debris removal frame to be driven synchronously, so as to grind and remove debris from the inside of the pipe groove, improve the internal environment of the pipe groove, avoid secondary construction, reduce labor, and facilitate the use of staff.

After the power connection is completed, the two grinding discs can be driven to rotate and the inner wall of the pipe groove can be polished to improve the flatness of the inside of the pipe groove, thereby improving the grooving quality and satisfying the current use.

[0027] (3) The grooving method for pre-buried pipelines of road bridges is to install a debris removal frame at the bottom of the lifting and pressure plate using a bracket, and to set a conveyor belt and a lifting plate inside the debris removal frame, which is used in conjunction with a material guide inclined pipe. The arrangement of these structures can use the bottom shovel plate to shovel together impurities during movement, and then use the material guide inclined pipe to discharge the impurities on the top of the road surface through transmission, thereby avoiding subsequent cleaning by staff and reducing workload.

[0028] (4) The grooving method for pre-buried road and bridge pipelines is characterized by installing water pipe racks at the front and rear of the cutting wheel, and providing nozzles at opposite angles on one side of the water pipe racks. The arrangement of these structures can spray the grooved area in a concentrated manner during grooving, effectively reducing the amount of dust, and can also be moistened for subsequent grinding, effectively improving the overall functionality of the equipment.

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0041] See also Figure 1-10 The present invention provides a technical solution: a grooving method for pre-embedded pipelines in roads and bridges, which specifically comprises the following steps:

[0042] S1. Position movement: Before use, push the moving carriage 101 in the basic linkage mechanism 1 to the construction point, and then adjust the direction in which the groove needs to be cut;

[0043] S2, start the descent: after the equipment is moved, the cylinder 208 in the grinding drive mechanism 2 is started, and the load-bearing frame 203 is pushed under the limit of the second slide plate 201 to drive the slotted wheel 206 and the cutting wheel 207 to descend to the ground, and at the same time, the synchronous plate 213 also drives the fourth rotating rod 215 and the second gear 218 to descend to the same height under the limit of the third slider 214 under the limit of the lifting port 219;

[0044] S3, spraying and grooving: after the grooved wheel 206 and the cutting wheel 207 are in contact with the ground, the water pump 221 and the motor 204 are started, and the motor 204 drives the cutting wheel 207 and the grooved wheel 206 to rotate and groove the ground. First, the cutting wheel 207 cuts at the edge to ensure the flatness, and then the grooved wheel 206 grooves in the middle. At the same time, when the nozzle 211 is started, the water in the water storage tank 220 is pumped out and injected into the inner side of the main water pipe 209, and then the nozzle 211 sprays water mist on the grooves of the cutting wheel 207 and the grooved wheel 206 to reduce dust;

[0045] S4, power docking: after the moving carriage 101 is pushed to move the slot for a certain distance, the threaded rod 103 is manually rotated, and the lifting and pressing plate 104 is driven to push the grinding disc 108, the impurity removal frame 113 and the first gear 111 to descend synchronously under the limiting action of the first slider 105. Since the slotting wheel 206 and the second gear 218 descend to the height that touches the bottom of the slot, the distance that the lifting and pressing plate 104 descends is the same as that of the slotting wheel 206. After the lifting and pressing plate 104 descends, the first gear 111 is meshed with the second gear 218, and at the same time, the grinding disc 108 descends to the bottom of the pipe groove and fits the side wall, and the bottom of the bottom shovel plate 122 is also in contact with the bottom of the inner cavity of the pipe groove. At this time, the power docking is completed;

[0046] S5, side wall grinding: after the first gear 111 and the second gear 218 are connected, the first gear 111 will use the first pulley 112, the first belt 123, the second pulley 115 and the second belt 116 to drive the first rotating rod 107 and the third rotating rod 114 to rotate at the same time. The rotation of the first rotating rod 107 will drive the two grinding discs 108 to grind the inner wall of the pipe groove to make it flat and neat when moving, and because the water mist is sprayed in advance, the generation of dust will be reduced;

[0047] S6. Impurity discharge: At the same time, the bottom shovel plate 122 contacts the bottom of the pipe groove. When following the movement of the moving carriage 101, the bottom shovel plate 122 will shovel impurities, dust and other stones to the bottom of the inner cavity of the impurity discharge frame 113, and the conveyor belt 118 is driven and rotated by the two transmission wheels 117. After the lifting plate 119 contacts the impurities, it rotates and transmits the impurities to the top of the impurity discharge frame 113. After the impurities reach the top of the impurity discharge frame 113, they are discharged on the surface of the road through two inclined material guide inclined pipes 120.
